Deactivation timer in a wireless device and wireless network

Abstract

A wireless device receives one or more messages comprising configuration parameters for a plurality of cells comprising a secondary cell. A deactivation timer may be disabled for the secondary cell in response to the configuration parameters comprising periodic resource allocation configuration parameters for configuring a periodic resource allocation of the secondary cell. A downlink control information (DCI) indicating activation of the periodic resource allocation may be received. The DCI may comprise a radio resource assignment. One or more transport blocks (TBs) employing the radio resource assignment may be transmitted.
